CORPORATON, OF DECATUR, ILLNOIS, A CORPORATION 0F ciirrrne Iviiiciiiivn,

Appiiation fiieaotober i1, 192e. sei-iai, No. iiogwiu4 rThis invention relates toa 'capping ma.- chine lfor applying caps to the necks or spouts of containers, and in which the caps are provided with alever which is turned down to 'fasten the cap upon the said neck or spout. l

Caps of this kind are applicable to all classes of containers so long as saidcont-ainers are provided with a properly yshaped neck or spout; and in machines oia this class, there is employed a cap holding and lever turning vdevice, and a container elevating device tor bringing the spout or neck of the container into engagement with the cap, ready for the lever turning operation; and in the machineherein shown the upward movement ofv the elevator forces the neck or spout into engagement with the cap and also causes the lever turning device to 'operate The object of the present invention is to provide gripping means for holding theneck or spout while the capping operation is be.- ing completed, in order to prevent the crushing ot the neck or spout or any displacement of the same; and with this object in view,

the invention consists broadly in providing a pair of gripping jaws which ai'e caused to grip the neck or spout and hold the same during the'capping and 'fastening operation, said gripping action being eil'ected by the movement ofthe container into position to receive the Vcap thereon.

The invention consists also in certain details of construction and novelties ot combination all of which will be fully described hereinafter and pointed-out in the claims.

In the drawing forming a part of the specification, Fig. 1 is a face view of a capping machine provided with this improvement; Fig. 2 is a side View of the same; Fig. 3 is a sectional plan view of the gripping jaws and actuating pins and Fig. 4 is a view showing the actuating pins and means for carrying the saine.

Referring to the drawings, 10 indicates the standard of al capping machine 11, the hopper for the caps and 12 the mechanism `for receiving said caps and turning the levers of the same, for the purpose oic fastening the cap upon the neck or spout 13 ot a container 14, said container being moved upwardly by means of a container elevator 15 for the purpose of forcing the neck or spout end into the cap setting thev lever turningdevice ink operation. 5 f 'l The type of cap-employed is shown in Will-iains Patent No. 1,108,959 anda capping machine of this type is shown in I-Iey, Webber and Le referment. iva-1,458,123,A it will be understood, however, that any machine o1"- this .general character can b'efemplo'yed and-'itl will also bev understood, that although f a sheet metal container -lias been illustrated, the invention is equally, as well adapted 'for glass` Y containers.

Carried by the container elevator, a-re'ltwo gripping jaws 16, 16, arrangedin parallel relation with their pivots 17, 17 intermediate their ends.

The forward ends of the jaws are cut out as shown at 18 to embrace the neck or spout 18 shown at 24 so'as to gradually spread the rear ends 19 and force the recessed portions 18 together, and the pins'21 are tormedvwith oppositely inclined portions 25 for the purpose of bringing the ends 19 together and separating the jaws 18'.

Y lf desired a spring 26 couldbe interposed j Y 'A between the jawsv to separate the same. Y

In operation, a cap Yisslipped into the chuck of the capping device and a container is placed upon the platform or rest ofthe elevator andthe machine in its` normaloperation causes the container to be moved upwardly until the neck or spout enters the cap and the continued upward movement causes the lever turning mechanism to turn the lever down and fasten the cap upon the neck or spout.

fis the container moves upwardly, the jaws 16 are separated at the rear ends and brought together at the ends 18 by the taper 21 of pin 20, contacting with ends 19, and these jaws 16 grip and hold the neck or spout during the entire period when pressure is applied thereto during the capping operation and if this neck ioo i v the neck o r spout of a containersaid jaws be-V ing pivoted outer-ends, of, said jaws.

described our invention, what means for engaging the rear ends of sai'djaws for bringing their forward ends together, means'engaging the rearends ofsaidjawsfor separating their forward ends,I said jaws being movable vertically, the opening and closing-means being stationary.A Y

2. In a device of the kind described'a pair oi jaws having the outer endsshaped` togrip intermediate theirY ends, a pin having a tapering end adaptedto-engag'efthe near ends of said-jaws to move the outer ends intogripping-v engagement with. a neck or spout, and pins having inclined portions for engaging said rear ends for .separating the 3. In a device of the kind described-the combination with a pair of' jaws pivoted intermediate their ends, of a pair of pins arranged upon opposite sides of said jaws at the rear ends, and a pin arranged between the rea-rv endso said jaws,.saidlpins having oppositely inclined portions at the lower ends, said pins and jaws being movable. with reference to each other whereby the outer gripping ends of the jaws are caused to move towards and away from each other.

4. Inv a device of the kind described, the

vcombination withy means for raising and lowering a container, of a pair of movable gripping jaws carried by and movable with said means, and stationary meansv for causing said jaws to move towardand away from each other as said raising and lowering means mov-es up'and down. l

In testimony whereof, we hereunto aiiix our signatures.
